What's new
Every release of Pier, newest first.
v1.5.0
Latest12 Jul 2026- /connection switches between your Pier subscription and your own key in one command, remembering the last model you used on each side instead of making you retype a full model slug.
- @-mentions are now honest about what they pulled in. Submit a message with @README.md or @src/ and a gutter under it shows exactly what was read, listed, or attached: files, directories, pasted images, and skills.
- New ultracode mode: turn it on and Pier fans a substantial task out across multiple agents working in parallel instead of working through it sequentially.
- Early groundwork for running Pier as a host, with a sandboxed runner for isolated execution, the foundation for running sessions outside your local machine.
v1.4.0
Release10 Jul 2026- Rewind a session, chat and files together. Press Esc twice to jump back to an earlier message, edit it, and resend. Pier restores the conversation to that point and can roll the working tree back to match, reverting edits and bringing back deleted files without touching work you have done since.
- Type ahead while the agent works. Queue up your next messages, reorder or edit them, and promote one to steer the running turn immediately, landing cleanly between steps rather than mid tool call.
- The resume picker is now searchable, with a short transcript preview of each past session so you can find and pick up the right one at a glance.
- A redesigned terminal experience with a cleaner layout, refreshed permission dialog, and model picker.
v1.3.0
Release10 Jul 2026- Commands can now reach the network safely: Pier detects when a command needs it (git push, curl, package installs and more), asks once, and runs it, with clear guidance instead of a silent failure when something is blocked.
- New Monitor watches: point Pier at a shell command, log stream, WebSocket, or HTTP endpoint and have it notify you when something you care about happens, so long-running work can run in the background and ping you when it is done.
- Background work now surfaces cleanly: a completion bell and notice, a live elapsed timer, and a named chip in the footer so you always know what is still running.
- The model picker now shows more at a glance: a (BYOK) tag on your own-key models, plus vision support and per-million pricing badges so you can compare before you switch.
- Cycle permission modes on the fly with Shift+Tab, mid-turn, without restarting the session.
- Richer automation hooks: auto-approve or rewrite a tool call before it runs, get notified before an approval prompt, react to subagent start/stop and file changes, and have Pier re-check its own work before it stops.
v0.1.0
Stable17 Jun 2026- First public release of Pier.
- Agentic multi-file edits with a built-in verification loop.
- Gateway planning mode: review the full edit plan before any file is touched.
- Rolling out to early-access developers in small batches.
